The waterproof blister plasters are new to the range. Care Plus® Blister Plasters are available in three sizes and shapes: Small, Medium and Finger & Toe. The Blister Plasters reduce pain and alleviate pressure. The blister remains free of water and dirt, allowing skin to recover. Use the blister plaster on clean, dry, and grease-free skin. The flexible and waterproof plaster remains in place for up to seven days. We recommend against removing the plaster until it falls off. Continue using the blister plaster until the blister is completely healed.
